In order to fix four minor problems like the following, remove the actions node from all subApps.

app: jcr-tools
from jcr
at /modules/jcr-tools/apps/jcr-tools
Source data processing problem: Property [actions] not found in class [info.magnolia.ui.form.definition.ConfiguredTabDefinition], property is not assigned: /subApps/dumper/form/tabs/mainTab

info.magnolia.jcrtools.JcrToolsBaseSubApp#onSubAppStart() builds a reduced form which doesn't require any actions. The default execute action is added by code in info.magnolia.jcrtools.JcrToolsViewImpl#build(). The actions in the configuration are most likely a copy&paste mistake.

Nodes:

• /modules/jcr-tools/apps/jcr-tools/subApps/dumper/form/tabs/mainTab/actions
• /modules/jcr-tools/apps/jcr-tools/subApps/exporter/form/tabs/mainTab/actions
• /modules/jcr-tools/apps/jcr-tools/subApps/importer/form/tabs/mainTab/actions
• /modules/jcr-tools/apps/jcr-tools/subApps/query/form/tabs/mainTab/actions
